351c, 2v or 4v?

Last year I bought a 1980 f150. The engine is a 351c that I was told came out of a 71' interceptor. How do I find out if I have 2v or 4v heads. I am also wanting to make some slight to medium modifications on it to increase horsepower and torque, what should I do?.

at each top corner of the heads you'll see a number cast in where the valve cover rounds off and the head stays square.

The casting number can tell you a bit about the part, compare to the list here. Note the 5th or 5th & 6th character is the only difference in some cases.

What manifold is on it? 2v or 4v? Look like a stocker?

Are you going to do a tear down, or just pile parts on it?

The number on the corner of the head is just a number to tell you if its 2v 4v.

It has the stock manifold. I am wanting to put on a high rise manifold, new headers and possibly a cam but not sure what to get on any of these. Any suggestions, (do note that this is a mud truck with 6'' lift and 33' swampers.)

it depends on if its a 2v or 4v. funnel web intake is a good high rise if you want to go that way.
